more readily understood from the Vfollow-` ing detailed description andaccompanying` drawings, in which, y Y

Figure 1 is a top plan view of a lire bar equipped with removable gratesections m accordance with the present invention.

Figure 2 is a vside, elevation ot' the construction shoWn in Figure 1. s

Figure 3 is a. longitudinal sectional view and,

Figure 4 is a transverse sectional view.

l-)reliminary to discussing the'sp'eciiic construction ol the iire bardisclosed herein it may be explained that in actual practicel a numberoit these lire bars are arrangedin spaced parallelism upon a suitablesupport and reciprocated through the instrumentality of a suitableoperating mechanism. This arrangement and operation ofthe iire bars iscovered in ymy co-pendingapplication and furtherdisclosure vthereof isnot deemed necessary to an understanding of the structure to Which thepresent invention kis directed.

As shovvn in the drawings the fire bar con sists ot a rectangularirame12 closed at the top by apluralityof inserted grate sections facilitythan the grate. sectionsv l 13 arranged end to end as shown in Figure i3 and provided with terminal -supportinglanges 14 'resting on thesupporting sur`l vfaces 15 afforded by the upperedges of theend-'membersy of the frame and the intermediate bridges 16 connectingthe sides votl the I trame. This arrangement obviously permits the gratesections 18 to be readily applied and removed.

As. shown to advantage in Figure 3 the vupper edge ot traine 12 forms acontinuous guard idliange 17 projecting above the supporting surfaces 15and having its upper surlace lush with the upper surface of the insertedgrate sections. This guard flange serves to lprotect the terminalflanges 14 and thesidcs oi' the inserted grate sections.

Having thus disclosed vvhat I now conceive to be. the preferredembodiment o'lithe invention it Will be understood that the variouschanges in the construction and arrangement o't parts may be resorted toWithin the 4scope ot the invention as defined by the appended claim.v

What Iielaim is: e

vA grate oi the character described comprising an openrectangularramehaving side and end membersV oi equal height, said end members beingArecessed at their inner upper edges to provide horizontal supportingsurfaces belou7 the upper lplane of the trame, spaced bridge membersconnecting the sides oil the iframe and having theirxupper edgesdisposed in the plane of said horizontal surtaces and a plurality ofgrate sections 'arranged in the frame in end to endk relation andprovided 'with terminal flanges*V supported by said horizontalsupporting surfaces and the-upperedges of the bridge members.
